	What is progressive scan? - A Word Definition From the Webopedia Computer Dictionary
		Progressive scan (also known as known as 480p) is one of two methods used for "painting" an image on a television screen (the other being interlaced scan), where the lines are drawn in one at a time in sequential order.
		Progressive scanning results in a more detailed image on the screen and is also less susceptible to the flicker commonly associated with interlaced scanning.
		Progressive scan is now the standard of choice for both DVD video and DTV.

	Line Doublers and De-Interlacers
		Interlaced scanning, painting 480 scan lines on the screen as two 240 line fields every 30/th of a second (for NTSC), was invented to get the best combination of horizontal resolution, vertical resolution, and freedom from flicker using the limited bandwidth of the TV broadcast channel.
		Because progressive scan has eliminated the flicker and fade of the odd scan lines as the even lines are drawn, feathered side edges as the subject moves are more noticeable.
		When progressive scan video is constructed using the weave method exclusively, viewers may see the feathered side edges of moving subjects, as the even scan lines show the subject in a dfferent position from the odd scan lines.

	Progressive Scan (Site not responding. Last check: )
		Progressive scan is supposed to reduce this problem.
		My experience so far using progressive scan has been on nights where the "seeing" was only average.
		Though this was taken at a low magnification (F10), which lessens the "wiggle factor", the "stair stepping" seen in the 1st progressive scan image example is evident.

		Which technique is selected will depend on the application and purpose of the video system, and particularly whether the system is required to capture moving objects and to allow viewing of details within a moving image.
		Interlaced scanning has served the analog camera, television and VHS video world very well for many years, and is still the most suitable for certain applications.
		Progressive scanning, as opposed to interlaced, scans the entire picture line by line every sixteenth of a second.

	What is Progressive scan 3/2 pulldown explained scanning help
		Because we are scanning at twice the speed, we can draw an entire frame in the same amount of time it takes an interlaced system to draw a single field.
		But with progressive, each "field" is now a complete picture including all scan lines, top to bottom, so we will now call it a frame, and we are showing 60 of those per second.
		The term commonly used to restore the progressive image is deinterlacing, though we think it is more correct to call it re-interleaving, which is a subset of deinterlacing.

	Hi Fi Writer - Progressive scan in PAL and NTSC
		Progressive scan is a genuine step forward for the NTSC picture format, but offers little for PAL viewers.
		Progressive scan means that the whole frame is drawn top to bottom in one continuous process, all 576 lines for PAL or 480 lines for NTSC.
		Where the progressive scan function is built into the DVD player, all this is done digitally, avoiding additional image-degrading digital to analogue, and analogue to digital conversions.

		Progressive scan refers to the way the image is displayed.
		The first pixel in the second line is next, followed by the rest of the second line and then the third line starting at the left, etc. until all of the lines of the image are displayed in sequence within 1/60 of a second.
		It is called "progressive scan" because the display of the image "progresses" across and down the screen uninterrupted.

	Panasonic Progressive Scan Explained
		Interlaced scanning combines two fields to generate a picture of 525 scan lines (480 of which are displayed).
		Your television projects an interlaced image by first scanning the 240 odd-numbered lines of one field (in 1/60th of a second), followed by the 240 even-numbered lines of the other field (in 1/60th of a second).
		Our progressive scan DVD players have a progressive video processor, which enables all 525 lines (480 of which are displayed) to be scanned at the exact same time; two interlaced fields are combined into one progressive frame.

	Guide to Progressive-Scan Technology (Site not responding. Last check: )
		This is called scanning, and each of the lines drawn by the electron beam is known as a scan line.
		Furthermore, the characteristic "flicker" associated with interlaced scanning (particularly problematic when the image contains fine horizontal details that are present in only one of the two interlaced fields) is noticeably reduced with progressive scanning, making it easier on your eyes.
		When an image moves quickly across the screen, the difference in its position from one field to the next becomes apparent, and the interlacing visually combines disparate fields, creating an effect known as "feathering" or "combing." Image definition becomes blurry and indistinct when movement occurs, but clarity is restored once the image becomes stationary again.

	Progressive-scan video - CNET reviews
		To illustrate the meaning of progressive scan, let's take a look at that old analog TV in your living room.
		Since the entire image is drawn at one time--as opposed to an interlaced image where the even lines are drawn first, followed by the odd lines--a progressively scanned video image looks more stable than an interlaced one.
		Progressive scan also introduces fewer motion artifacts, such as jagged diagonal lines and movement in fine detail, into the picture.

	Progressive Scan Definition
		Therefore, a progressive scan video signal sends twice as much data than an interlaced signal each time it draws an image on the screen.
		Still, if a progressive scan and interlaced image are both projected at 60 Hz, the progressive scan image will usually appear slightly smoother.
		When you see video formats described as 480p or 720p, the number indicates how many horizontal lines of resolution the video signal uses, while the "p" indicates it is a progressive scan signal.

		Each progressive video frame is reconstructed by weaving together the odd and even fields from images that were derived from the same film frame.
		Because many computer displays are capable of broader ranges of horizontal and vertical scan rates, it is possible to create temporally symmetrical progressive video that runs at two or three times the film's frame rate: 48 or, more commonly, 72 frames per second.

		The odd lines are scanned (drawn on the screen) in 1/60th of a second, and the even lines follow in the next 1/60th of a second.
		Interlaced scan splits the image into two fields, alternating between the even (2,4,6) and odd (1,3,5) scan lines every 1/60th second, and effectively displaying a full frame every 1/30th second.
		Progressive scan, on the other hand, displays all the lines at once (1,2,3,4), displaying a full frame every 1/60th second.
